7 Claims. (Cl. 273—81.3)
A golf putter embodying my invention is provided with
a shaft 1, having an upper portion la and a lower portion
1b. Said portions are substantially of equal length and
subtend a substantial oblique angle between them. The
point of joinder between said portions presently is round
ed upon a smooth sweep 1c. A club head 2 is joined to

speci?cally to that type of putter which is used croquet
mallet-style with the golfer facing the line of the putt and 10 to the upper end of the upper portion of the shaft, in the
usual manner. Except for the obliquely angular relation
with his feet straddling the projected line. The ball is

in a horizontal plane with the shaft extending upwardly
therefrom. Golf putters of this general type have been
designed and used in a limited way, but have not been
widely accepted. They are legal and authorized under
United States Golf Association rules and regulations.
The lower portion 1b of the shaft is joined to the club
head at substantially its midpoint 2a. Said club head
preferably is elongated, massive and has a striking face 4
of rectangular shape, having a width slightly less than the
diameter of a golf ball. I have found that a good rela
tionship of Width to length of such striking face is one
it is my observation that such a putter should hang
inch by three inches. The sole 5 of the putter head is
pendent from a golfer’s hands, should be so proportioned
preferably of sled-runner shape. That is, it terminates at

smooth curve towards the trailing edge 6 of the club head.
the ball may be stroked with a pendulum swing with the
elbows lightly touching the sides of the body. If the
putter shaft is straight or substantially straight it is pos
The back of the club head is preferably provided with
a ?ange 7a so that substantial mass lies directly behind
sible for the shaft to rotate on the back swing so that the
the point of ball impact with the club face. Such dis
putter head may become out of square with the projected
line of ?ight and out of alignment therewith. I have dis
covered that if the putter shaft has a decided bend at its
?ange also provides a sole of substantial width, fore and
aft, that is, at right angles to the striking face so that the
midpoint that the putter may hang comfortably in
addressing the ball, will not rotate, will remain square
back swing or upon the forward swing. Although this
with the line of ?ioht and swing in alinement therewith.
It is therefore a principal object of my invention to
provide a golf putter which when hanging plumb from
a golfer’s hands will have the lower portion of the shaft
in line with the golfer’s eyes and with the back of the golf
ball. Said lower half of the shaft will incline rearwardly
towards the putter head and, due to said conformation
of the putter, may be moved backwardly low upon the
ground without rotating and without wavering from a
projected line along which the golfer intends the golf
ball to roll. A putter thus arranged also puts substantial
overspin upon the ball due to the shape of the shaft and
the face of the golf club so that a golf ball struck with a
putter so constructed will follow the putting line and fol
low its projected line of ?ight.
Further features of my invention and the details there
of are hereinafter described with reference to the accom
panying drawings, in which:
position of mass provides low swinging weight.
Said
putter does not tend to catch the turf either upon the
conformation of the putter head in lateral cross section
is preferred, it is not essential.
The lower portion 1b of the shaft extends substantially
at right angles to the upper face 8 of the putter head. The
striking face is provided with approximately a 10° loft as
is illustrated in FIG. 4. This is not true loft which would
tend to give back spin to the ball, because when the club
is held pendent, as is illustrated in FIG. 2, a plumb line
extends from the upper end of the grip in parallelism with
the striking face 4 and the lower end of the shaft slopes
forwardly down the line of putt at an angle of approxi
mately 10".
The upper and lower portions of the shaft subtend an
included angle x, as is illustrated in FIG. 3, of approxi
mately 150". That is to say, the upper and lower por
tions of the shaft are out of alinement with each other
approximately 30° from a straight line. In a putter hav
ing a shaft approximately thirty-four inches long the de
?ection A from the plumb line is three and one-half to
four inches. This angle and degree of de?ection is not
55 critical. It is merely illustrative of a preferred arrange

the line to the cup.
I have found that with a putter having the angular de
?ection of the two portions of the shaft, the length sug
gested and the upward angularity of the striking face of
the putter will permit comfortable and e?icient use by sub
stantially all golfers, both men and women. Of course,
a slight adjustment may be made to suit the individual
golfer by arranging the hands upon different parts of the
